hello my name is Ariana and I want to tell you about a horse.
There are about 75 million horses in the world.
Horses' hooves grow approximately 0.25 in a month, and take nearly a year to grow from the coronet band to the ground. Did you know In the state of Arizona, it is illegal for cowboys to walk through a hotel lobby wearing their spurs! A healthy adult horse should have a pulse of between 36 and 40 beats per minute while at rest . Arabians have one less rib, one less lumbar bone, and one or two fewer tail vertebrae than other horses. Adult respiratory rate is 8-16 breaths per minute
A horse typically sleeps two and half to three hours a day. Horses younger than 4 years can concentrate for a maximum of 10-15 minutes. Horses lie down only about 43.5 minutes a day . Horses sleep longer in the summer than in the winter. A horse’s heart weighs nine pound
s.
The horse is a herbivorous mammal. All horses (including zebras) belong to the genus equis. Horses began to evolve on the American continent over 60 million years ago, they later died out and were reintroduced by Spanish settlers. I hope you like it.





whales
hello my name is Ariana and I want to tell you about different kinds of whales
Whales are mammals, so they feed milk to their babies and breathe air. Sperm Whales have the largest brain on the planet. It may weigh 20 pounds. The fin whale is one of the fastest whales. They can swim over 20 miles per hour for short periods.
The blue whale is the largest whale. They may grow up to 100 feet and weigh as much as several elephants.The harbor porpoise is one of the smallest whales. They grow to only about 5 feet in length.Killer whales are the largest dolphins. They get their name because they sometimes eat other, larger whales.A humpback whale may eat up to a ton of food every day.Whales can't breathe through their mouths. The mouth is connected directly to the stomach. They breathe through their blow holes, which go to the lungs.A sperm whale can hold its breath for at least an hour.The voice of the blue whale is one of the deepest voices on the planet. It is so powerful that it can travel for perhaps a hundred miles underwater.The blubber on a whale which lives in very cold water may reach up to 20 inches thick. It is used to insulate the whale and also as an emergency food store.Whales do not spout water. They are letting out air from their lungs. The warm air forms a cloud, like ours does in the winter. As it comes out it will also push any water which is covering the blow hole high into the air.A new born baby blue whale may weigh two tons and be 25 feet long.When whales sleep, they stay at the top of the water, with their blowhole above the surface. Sometimes, a whale will swim up to the surface of the water and quickly blow air out of their blowhole, making a fountain of watery mist, called a “blow.”The baleen plates grow from the whales’ upper jawbones. They are from two to 12 feet long and they hang down in stringy pieces. Sea water passes through the baleen and the whales’ food gets caught. A kind of plankton called krill is what the baleen whale eats. The biggest baleen whales eat as much as two tons of krill each day! Baleen whales have two nostrils, or blowholes. These are facts about a lout of different whales and I hop you enjoyed it. Bye

Hello I want to tell you about Lions!!
A lion is Lions belong to the Panther Leo Species.Lions have 3-4 lion cubs in an average litter. A single lion needs approximately 10-20 large animals per year to sustain it.
Most lion hunts fail. Of 62 lion stalks observed in one study, only 10 were successful.Lions are the only animal in the cat family who have manes. Only the male lions have manes though.Male lions have manes to make them look fierce and to protect their throats when fighting with another male.The Darker a lions mane, the older he is.Lions remain inactive for up to 20 hours a day. They wait for the coolest, darkest times to hunt.Unlike most cats, lions are excellent swimmers.When lions walk, their heels don't touch the ground.A typical meal for a lion is 15 Lbs of meat, but they can eat a meal up to 60 Lbs.Lions drink with their tongues and it usually takes about ten minutes for a lion to drink.Tigers are lion's closest relatives. Without their coats, lion and tiger bodies are so similar that only experts can tell them apart.A lion's roar can be heard up to five miles away.Lions remember each other from their scents. When they rub their heads on each other, they transmit their personal odor on the other members of the group.Lions are the only social cats, living in groups called prides.Male lions are the only cats with manes - a trait of which the origin and purpose has divided scientist. Living in prides helps lions survive in difficult times, proving particularly beneficial for the vulnerable young cubs that need protection. Lion cubs have spots at birth that disappear with age.In the pride, lionesses specialize in hunting whereas the big males' function is to provide protection from outsiders. Lions take down a variety of prey animals including gazelles, wildebeest, buffaloes and even elephants in certain parts of Africa (e.g. Botswana). Lions do not like competition and frequently attack and kill fellow predators like leopards, hyenas and cheetahs. Contrary to popular belief, recent research indicates male lions take part in 50-60% of hunts - particularly when it's required to bring down larger prey. Also there is increasing evidence that lions do scavenge and frequently attack hyenas to steal their kills. Though not as notorious as tigers for man-eating, lions do at times resort to attacking people - displaying great cunning and bravery ~ as seen in the case of Tsavo man-eaters nearly a century ago.A pride comprises of interrelated females and one to four adult males ~ young male lions are kicked out of the pride when they show signs of maturity. These young males, known as nomads, then wander around, forming coalitions and surviving on their own until they reach enough strength and maturity to take over a pride of their own.Lion is known as the king of beasts for his bravery and fighting skills!
The lion is a member of the cat family, and shares many common traits of this family. The body is very muscular, with less bone mass than other animals of comparable size. This is also responsible for the grace of movement we associate with members of the cat family. The forebody of the lion is very powerfully built, and has the greatest forebody strength of any cat, except possibly the tiger. This enables the lion to deliver blows with it's forepaws heavy enough to break a zebra's back. The bones of the front legs are twisted in such a manner as to give a great range of motion to the forelimb.
Each paw is equipped with soft pads to make it's movements quiet. Like most carnivores, lions are digitigrade walkers. This means they essentially walk on their toes. But, the majority of the animal's weight is borne by the main paw pads, which would correspond on a human to the palm of the hand at the base of the fingers. Extra bones in the toe joints give the toes a wide range of motion.The claws are retractible and very sharp. The retractable feature helps keep the claws sharp, and prevents injury during play, etc. The dewclaw on the front limbs is often used as a toothpick. The claws grow as a series of layers. As a layer wears, it is shed, and a new sharp-pointed claw is exposed. The claw on a large lion can be 1 1/2 inches (38 mm) or more from base to tip along the curve.
The body is covered with a sandy brown coat in most subspecies of lions, but there is a white variant that shows up once in a while, especially in the Timbavati region of South Africa. (The white variant is also showing up more and more among captive lion populations.) Lions with a very dark brown coat have been observed, but this is quite rare. The coat color of a lion is not determined so much by the color of the hair, but by the ratio of light-colored hairs to dark-colored hairs.
The mature male lion has a mane that covers the backside of the head, and the shoulders. The extent of the mane varies from individual to individual, with some having no mane at all, while others have a luxurious mane that runs onto the body, along the abdomen, and even onto the fronts of the back legs in exceptional specimins. The mane varies in color from the rest of the body, and tends to grow darker with age. Some lions in the Serengeti area and from North Africa have a nearly black mane. Just like th body hair, the mane color is determined by the ratio of dark hairs to light hairs present. The mane hair is stiff and wiry, like stiff horeshair. Besides it's primary role of protecting the male during fights, it has been discovered that female lions prefer males with bigger and darker manes.
The eyes are proportinately larger than in other comparable-sized animals, and posess round pupils. Lions, like most cats, are visual animals. The eyes are also well-adapted for use under very low light. This helps the lion hunt at night. Contrtry to popular notion, a lion's eyes do not glow in the dark, but they contain a special reflective coating that will reflect even moonlight. This coating increses the lion's visual acuity in very low light by ensuring that every possible photon of light makes it to the cells in the retina. Their eyes are effective even by starlight. A white circle just below the eyes helps reflect light into the eyes to further improve night vision. Like most mammals, lions have a nictitating membrane which serves to clean and protect the eye in some circumstances. Lions, like most cats, have limited ability to move their eyes side-to-side, and must turn the head to look in a different direction.
The sense of smell is well developed. Lions mark their territories by means of scent deposits, necessitating a good sense of smell. This also helps them find kills made by other predators, and perhaps obtain an easy meal by driving the other predator off their kill. Another interesting thing that lions and all other cats posess is a special olfactory organ on the roof of the mouth called a Jacobson's organ. Sometimes, you will see a lion, or even your cat, grimace when smelling something. They are opening their lips to draw air over their jacobson's organs. This grimacing gesture is called Flehmen. The sense of hearing is perhaps only slightly above average. The ears can be swiveled over a wide angle to enable the lion to hear distant sounds, and know what direction they are coming from.
The lion's tail is the only one in the cat family with a tassel at the tip. (Ligers also have a tassel, but they are not found in the wild.) This tassel conceals a spine, which is the last few tail bones fused together. What function this spine serves, if any, is unknown. The tail is very important for overall balance. Females also use their raised tail as a 'follow me' signal for the cubs. They also use it to signal each other during a group hunt.
The lion's teeth are well adapted for killing their prey and eating it. The great canine teeth are spaced such that they can slip between the cervical vertebrae of their favorite-sized prey animals, and sever the spinal cord. The shape of the back teeth, which are called carnassals instead of molars, makes them work like a pair of scissors, for cutting pieces of meat. The jaw is not capable of moving side-to-side, like ours. This helps keep the carnassal teeth in alingment for cutting. The rest of the teeth are conical, and designed for cutting and tearing
. Lions, like all cats, do not chew their food ,but swallow it in chunks. This lioness is 'Sierra' at the Sierra Safari Zoo in Reno, NV. They also use only one side of their mouth at a time. This trait is also common to all cats, and is caused by the inability of the jaw to move side-to-side. The tongue is covered with rough spines, called papialle. This helps the lion scrape meat off of bones, and acts like a comb for grooming.
The digestive system of the lion is simple, not unlike a human's. Meat is fairly easy to digest, and the elaborate digestive mechanisms present in their prey for breaking down celluose are not needed. Cats, in general have the shortest digestive tracts of all animals.
A lion's body temperature ranges from 100.5 to 102.5 degrees farenheit. (38.05 - 39.16 degrees C.)
No physical description of the lion would be complete without some mention being made about it's magnificent roar. Only four cats can roar: The lion, tiger, leopard, and jaguar. These four cats have been assigned to the genus Panthera because they can roar. Of these cats, the lion roars the most. It is beleived the roar serves to alert other lions of an individual's presence. Roaring choruses of several lions, or a whole pride, also take place. When a lion roars, it can do so with enough force to raise a cloud of dust. Roaring is made possible by a special two-piece hyoid bone in the throat. All of the non-roaring cats have a one-piece hyoid bone. It is said that a lion's roar can be heard 5 miles
(8 km) away.
I hope you liked it.Bye

I will tell you about Dolphins.

Like a bat, dolphins use echolocation to navigate and hunt, bouncing high-pitched sounds off of objects, and listening for the echoes. An excerpt from the World Wildlife Fund 2005 concerning the order Cetacea, which includes both whales and dolphins: "The greatest threat to whales, dolphins and porpoises is entanglement in fishing gear, also known as bycatch. If current trends continue unabated, several cetacean species and many populations will be lost in the next few decades."Fish and squid are the diet of the common dolphin, where the dolphins have been seen hunting and working together to herd the fish into tight balls. Dolphins sleep with one half of their brain plus one eye closed, then switching to the other side of the brain and the other eye closed during other parts of the day slowing down everything inside their bodies and moving very little. Because the spinner dolphin swims with the yellowfin tuna, they have been slaughtered by the hundreds of thousands in the purse-seine tuna fisheries, which has produced the controversy that led to the enactment of national and international laws for dolphin safe tuna. Baby dolphins are sucked forward by the motion of their swimming mothers giving them a needed assist when they position themselves to the right and behind their mothers. Thought to be one of the most intelligent and beautiful creatures in our oceans and rivers, dolphins also take on a persona that is adored worldwide. We see them jumping, playing, and even hear them laughing as they have fun in the ocean. Dolphins are some of the most highly intelligent creatures on earth. These warm-blooded mammals belong to a group of mammals called Cetaceans which also encompass all whales. Dolphins are referred to as "toothed whales" or Odontocetes differentiated from Baleen whales which have horny plates connected to their upper jaw. Dolphins come in different colors and sizes. dolphins cannot actually sleep because they need to be conscious to breathe. Instead of going into a deep sleep where they would suffocate themselves, they often left half of their brain sleep at one time and then the other half at another time. In this way, dolphins are able to “sleep” about eight hours per day. dolphins have to come up to the surface to breathe? Most dolphins surface every few minutes, but they can stay under water for up to 15 minutes. A dolphin breathes through the blowhole on top of its head. dolphins evolved from land animals? The land ancestor of the dolphin lived about 50 million years ago and looked a little like a wolf. This animal hunted in shallow waters and by and by adapted itself to life in water: the forelegs became flippers, the hindlegs disappeared and the fluke evolved, the fur disappeared and the nostrils moved to the top of the head. dolphins use echolocation to navigate and to find food? Dolphins send out clicks that are returned from other objects in the water (just like an echo). This way a dolphin can locate food, other dolphins, predators or rocks. dolphins live in families? These families are usually led by a female dolphin. The dolphins in a family help each other, for example when raising their young. When travelling or hunting, several families might join together to make a larger group, a school of dolphins.the largest dolphin is the orca? It can reach up to ten metres in length. dolphins have a thick layer of fat beneath their skin? This layer of fat is called blubber. As dolphins have no fur, they need the blubber to keep warm. Dolphins in colder waters usually have a thicker layer of fat than dolphins in warm waters. dolphins are endangered? Humans are the greatest threat to dolphins: environmental pollution, habitat destruction and overfishing are the main reasons why so many dolphin species are endangered. Lots of dolphins get stuck in fishing nets and in some countries, dolphins are deliberately killed because they eat the fish that the fishermen want to catch. If we do not do anything about it, dolphins might soon be extinct. not all dolphins live in seawater? There are some species that live in fresh water: the river dolphins. Unfortunately, river dolphins are critically endangered and it is even feared that one species, the baiji, has already died out. you can help to protect dolphins? Educate yourself about these animals and tell others about them. Care more about our environment and start to recycle more things. Raise money for an organization that helps to support dolphins. Dolphins belong to a group of mammals referred to as cetaceans (or Cetacea). The cetaceans are further broken down into two main groups, the toothed whales (or Ondontoceti) and the baleen whales (Mysticeti). Dolphins are classified as toothed whales (Onomatopoetic. Other toothed whales include killer whales, pilot whales, beluga, narwhal, sperm whales, and several groups of river dolphins. The term 'dolphin' refers to a diverse assortment of marine mammals. The term dolphin is not restricted to a single taxonomic class and therefore is an unspecific term. The groups of toothed whales whose members are often referred to as dolphins include the oceanic dolphins (Delphinidae), river dolphins (Iniidae), and the Indian river dolphins (Platanistidae). Of these groups the oceanic dolphins are by far the most diverse. Oceanic dolphins are also referred to as 'true dolphins' and are the most diverse group of cetaceans. The species of dolphins that belong to the Family Delphinidae are referred to as 'oceanic' or 'true' dolphins. The Delphinidae group includes about 32 species and is the largest of all subgroups of the cetaceans. Species of oceanic dolphins (Delphinidae) inhabit the open ocean, though this is not a strict rule for the group (in some cases, oceanic dolphins inhabit coastal waters or riverine habitats). Some oceanic dolphins have a prominent beak also known as a 'rostrum'. The snout of some oceanic dolphins is long and slender due to their elongated, prominent jaw bones. Within the dolphins' elongated jaw bone sits numerous conical teeth (some species have as many as 130 teeth in each jaw). Species that have prominent beaks include, for example, Common Dolphin, Bottlenose Dolphin, Atlantic Humpbacked Dolphin, Tucuxi, Long-Snouted Spinner Dolphin, and numerous others. A dolphin's forelimbs are known as 'pectoral flippers'. The forelimbs of a dolphin are anatomically equivalent to the forelimbs of other mammals (for example, they are analogous to arms in humans). But the bones within the forelimbs of dolphins have been shortened and made more rigid by supporting connective tissue. Pectoral flippers enable dolphins to steer and modulate their speed. Some dolphin species lack a dorsal fin. The dorsal fin of a dolphin (located on the back of the dolphin) acts like a keel when the animal swims, giving the animal directional control and stability within the water. But not all dolphins have a dorsal fin. For example, the Northern Rightwhale Dolphins and the Southern Rightwhale Dolphins lack dorsal fins. Dolphins have a unique sense of hearing. Dolphins do not have prominent external ear openings. Their ear openings are small slits (located behind their eyes) which do not connect to the middle ear. Instead, scientists suggest that sound is conducted to the inner and middle ear by fat-lobes located within the lower jaw and by various bones within the skull. Dolphins have excellent vision in and out of the water. When light passes from air to water, it changes speed. The creates an optical effect referred to as refraction. For dolphins, this means their eyes must correct for these differences if they are to see clearly in both conditions. Fortunately, dolphins have specially adapted lens and cornea that enable them to see clearly in and out of the water. The Baiji is a critically endangered river. Dolphins probably do not have a very strong olfactory sense. Dolphins, like all toothed whales, lack olfactory lobes and nerves. Because dolphins do not possess these anatomical features, they most likely have a poorly developed sense of smell. Dolphins are beautiful creatures. I hope you liked it. BYE
